Re: MPH with MDS on WK2?
I have posted a document I found about the MDS when researching the 2011 Grand Cherokee and the Hemi V-8. It seems to be from informed sources, although the author is not identified. It is not definitive about when MDS is on/off as per this thread, but notes speeds as high as 90 MPH. The document is attached in the ZIP file.
The MDS system is designed to operate at speeds from around 20 mph to 80 mph. Some owners have reported activation at speeds up towards 90 mph.
